When a restrained patient spits, it creates a complex crisis involving physical danger and a significant biohazard risk. Staff safety from infectious material and the patient’s well-being during the intervention are the two main priorities. A coordinated response is necessary to mitigate the risk of pathogen transmission while ensuring physical control measures do not cause harm. Staff must execute trained procedures for both immediate biohazard containment and safe physical restraint.
Prioritizing Immediate Staff Protection
The first action is to implement biohazard protection for staff members. Staff must immediately wear appropriate Personal Protective Equipment (PPE) to create a barrier against splashes. This includes a fluid-resistant surgical mask or N95 respirator, and specialized eye protection like goggles or a full face shield.
If the patient is already restrained and begins spitting, the team should apply a dedicated fluid containment mask over the patient’s face. A standard surgical mask or any unapproved device should not be used for this purpose, as it may interfere with breathing or pose an aspiration risk if the patient vomits. The fluid containment device must be designed to safely contain the fluid while allowing for unimpeded respiration and continuous observation of the patient’s face and airway.
If a staff member is exposed to saliva before a barrier is deployed, immediate decontamination is required. Contaminated clothing should be removed quickly, and exposed skin thoroughly washed with soap and water. If the saliva contacted the eyes, nose, or mouth, those mucous membranes must be flushed immediately with water or saline for several minutes to reduce the potential for infection transmission.
Maintaining Safe Physical Control
Once the biohazard risk is mitigated, the focus must shift to maintaining safe physical control of the patient to prevent injury. A primary concern during any physical restraint is the risk of positional asphyxia, where the patient’s body position restricts their ability to breathe adequately. This risk is elevated when a patient is restrained in the prone, or face-down, position, especially if pressure is applied to the back or abdomen.
To minimize this danger, staff must avoid placing weight on the patient’s torso and should transition the patient out of the prone position quickly. The patient should be moved to a supine (face-up) position, or preferably a side-lying or seated position, which allows for maximum chest wall expansion and easier monitoring. Restraint should only employ the minimum force necessary to maintain control and must be executed by a trained team using approved methods to prevent injury to the patient’s limbs or joints.
Monitoring of the patient’s physiological status is required for the duration of the restraint. Staff not actively engaged in the hold must check the patient’s airway, breathing, and circulation frequently (a minimum check every 15 minutes for behavioral restraints). Signs of distress, such as cyanosis, gurgling, gasping, or a sudden calmness following a struggle, must be recognized as potential indicators of positional asphyxia.
Even while physically controlled, staff must continue verbal de-escalation, speaking calmly and consistently. This engagement reduces the patient’s agitation and anxiety, lowering physiological stress and the need for continued physical intervention. The restraint must be discontinued the moment the patient is no longer presenting a risk of harm to themselves or others.
Required Post-Incident Procedures
After the confrontation concludes and the patient is secured, several administrative, medical, and psychological steps must be executed. Documentation must begin immediately, creating a detailed record of the patient’s behavior, the rationale for the restraint, the type and duration of the hold, and all de-escalation efforts. This record must also include a specific note regarding the biohazard exposure, detailing the staff members involved and the route of contamination.
For any exposed staff member, a post-exposure protocol must be initiated without delay, involving a risk assessment by an infection control professional. This protocol includes testing the exposed staff member and, if feasible and legally permissible, the source patient for blood-borne pathogens such as Human Immunodeficiency Virus (HIV) and Hepatitis B and C. Post-exposure prophylaxis (PEP) medications must be offered and administered as soon as possible (within 24 to 48 hours of exposure) to be most effective.
A physician or authorized healthcare practitioner must perform a medical assessment immediately following the restraint to check for injuries. This assessment determines the patient’s need for further medical or psychiatric intervention, including potential chemical sedation, and confirms physical well-being was maintained. Finally, all staff involved should participate in a formal debriefing session to manage incident stress and review the response for opportunities to improve future safety protocols.
